[0014] Compared with the prior art, the beneficial effects of this utility model are: the high mechanical strength magnetic core not only facilitates the guidance and fixation of the left and right magnetic cores, but also improves heat dissipation efficiency and stability; By setting a limiting groove, a guide rod, a first reserved groove, a fixing rod, and a guide groove, the guide rod and the limiting groove are aligned when the left and right magnetic cores are spliced. After alignment, the right magnetic core is pushed, and the guide rod slides inside the limiting groove. The guide rod and the limiting groove can guide the right magnetic core, making it convenient for the left and right magnetic cores to be aligned and spliced.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 The present invention provides an embodiment of a high mechanical strength magnetic core, comprising a left magnetic core 1, a right magnetic core 8 disposed on the right side of the left magnetic core 1, a guide rod 6 fixedly connected to the top of the left side of the right magnetic core 8, a limiting groove 5 formed at the top of the right side inside the left magnetic core 1, a first reserved groove 7 formed at the bottom of the front end of the right side inside the left magnetic core 1, a guide groove 22 formed at the bottom of the right side inside the left magnetic core 1, a winding post 2 installed at the top of the right magnetic core 8, a connecting block 3 fixedly connected to the top of the winding post 2, and a fixing rod 20 fixedly connected to the front end of the connecting block 3. The first reserved groove 7 is set at the front end of the guide groove 22, the connecting block 3 slides left and right inside the guide groove 22, the guide rod 6 is embedded inside the limiting groove 5, the guide rod 6 slides inside the limiting groove 5, and the fixing rod 20 slides inside the first reserved groove 7. Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, when splicing the left magnetic core 1 and the right magnetic core 8, the guide rod 6 and the limiting groove 5 are aligned. After alignment, the right magnetic core 8 is pushed, and the guide rod 6 slides inside the limiting groove 5. The guide rod 6 and the limiting groove 5 can guide the right magnetic core 8, making it convenient for the left magnetic core 1 and the right magnetic core 8 to be aligned and spliced. When the guide rod 6 slides inside the limiting groove 5, the fixing rod 20 and the connecting block 3 will slide inside the first reserved groove 7 and the guide groove 22 respectively. This not only makes it convenient for the winding post 2 to be installed between the left magnetic core 1 and the right magnetic core 8, but also further improves the guiding effect and prevents the left magnetic core 1 and the right magnetic core 8 from shifting during splicing.

[0019] A mounting block 11 is fixedly connected to the bottom left side of the right magnetic core 8. A mounting groove 12 is opened at the bottom inside the left magnetic core 1. Limiting slots 13 are opened at the upper and lower ends inside the mounting groove 12. A reset spring 14 is installed inside the mounting block 11. A damper 15 is installed inside the reset spring 14. A connecting plate 17 is fixedly connected to the upper and lower ends of the reset spring 14 and the damper 15. A limiting block 16 is fixedly connected to the end of the connecting plate 17 near the outside. A pull plate 18 is fixedly connected to the front end of the connecting plate 17. A second reserved groove 19 is opened at the upper and lower ends of the front end of the mounting groove 12. The mounting block 11 is embedded inside the mounting groove 12. The limiting block 16 is embedded inside the limiting slot 13. The pull plate 18 slides up and down inside the second reserved groove 19. The mounting block 11 is fixed inside the mounting groove 12 by the limiting block 16 and the limiting slot 13. Specifically, such as Figure 1 and Figure 2 As shown, when the pull plate 18 is pressed, the pull plate 18 drives the connecting plate 17 to squeeze the reset spring 14, causing the limiting block 16 to move towards the center. After the mounting block 11 is embedded in the mounting groove 12, the pull plate 18 is released. The reset spring 14, through its own elasticity, causes the limiting block 16 to be embedded in the limiting groove 13, thereby fixing the mounting block 11 in the mounting groove 12 to splice and fix the left magnetic core 1 and the right magnetic core 8.

[0020] Heat dissipation grooves 9 are provided on the left and right edges of the bottom end of the right magnetic core 8. Wire holes 10 are machined on the left and right sides of the bottom end of the right magnetic core 8. A hinge block 4 is movably hinged to the top of the front end of the right magnetic core 8. A groove 21 is provided at the bottom of the inside of the hinge block 4. The bottom of the hinge block 4 is locked to the outside of the fixing rod 20 through the groove 21. Specifically, such as Figure 1 and Figure 4As shown, the heat dissipation groove 9 inside the right magnetic core 8 can dissipate heat during operation, thereby extending the service life of the magnetic core. After fixing the left magnetic core 1 and the right magnetic core 8, rotate the hinge block 4 so that the fixing rod 20 at the bottom of the hinge block 4 is locked outside the groove 21 to limit and fix the groove 21, further improving the stability of the winding post 2 installed between the left magnetic core 1 and the right magnetic core 8.

[0021] Working principle: When using this invention, the guide rod 6 and the limiting groove 5 are aligned when the left magnetic core 1 and the right magnetic core 8 are spliced. After alignment, the right magnetic core 8 is pushed, and the guide rod 6 slides inside the limiting groove 5. The guide rod 6 and the limiting groove 5 can guide the right magnetic core 8, facilitating the alignment and splicing of the left magnetic core 1 and the right magnetic core 8. When the guide rod 6 slides inside the limiting groove 5, the fixing rod 20 and the connecting block 3 will slide inside the first reserved groove 7 and the guide groove 22 respectively. This not only facilitates the installation of the winding post 2 between the left magnetic core 1 and the right magnetic core 8, but also further improves the guiding effect and prevents the left magnetic core 1 and the right magnetic core 8 from shifting during splicing. Pressing the pull plate 18 causes the pull plate 18 to drive the connecting plate 17 to squeeze the reset spring. Spring 14 moves the limiting block 16 towards the center. After the mounting block 11 is embedded in the mounting groove 12, the pull plate 18 is released. The return spring 14, through its own elasticity, causes the limiting block 16 to be embedded in the limiting groove 13, thereby fixing the mounting block 11 inside the mounting groove 12 to splice and fix the left magnetic core 1 and the right magnetic core 8. The heat dissipation groove 9 inside the right magnetic core 8 can dissipate heat during operation, thereby extending the service life of the magnetic core. After fixing the left magnetic core 1 and the right magnetic core 8, rotate the hinge block 4 so that the fixing rod 20 at the bottom inside the hinge block 4 is locked outside the groove 21 to limit and fix the groove 21, further improving the stability of the winding post 2 installed between the left magnetic core 1 and the right magnetic core 8.
